Quantiles
Calculate quantile of a specific value.
Mean & variance
As we have "full" histogram, we can calculate other statistical variables.
Mean.
mean (tdigest [1..100] :: TDigest 10)Just 50.5
Note: if you only need the mean, calculate it directly.
Variance.
Standard deviation, square root of variance.
CDF
Cumulative distribution function.
Note: if this is the only thing you need, it's more efficient to count this directly.
